CVE-2010-4073

Status Candidate

Overview

The ipc subsystem in the Linux kernel before 2.6.37-rc1 does not initialize certain structures, which allows local users to obtain potentially sensitive information from kernel stack memory via vectors related to the (1) compat_sys_semctl, (2) compat_sys_msgctl, and (3) compat_sys_shmctl functions in ipc/compat.c; and the (4) compat_sys_mq_open and (5) compat_sys_mq_getsetattr functions in ipc/compat_mq.c.

Ubuntu Security Notice USN-1202-1
Posted Sep 14, 2011
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1202-1 - Dan Rosenberg discovered that several network ioctls did not clear kernel memory correctly. A local user could exploit this to read kernel stack memory, leading to a loss of privacy. Brad Spengler discovered that stack memory for new a process was not correctly calculated. A local attacker could exploit this to crash the system, leading to a denial of service. Dan Rosenberg discovered that the Linux kernel TIPC implementation contained multiple integer signedness errors. A local attacker could exploit this to gain root privileges. Various other issues were also addressed.

Linux Kernel Econet Privilege Escalation
Posted Sep 6, 2011
Authored by Jon Oberheide

This exploit leverages three vulnerabilities to escalate privileges. The primary vulnerability is a kernel stack overflow, not a stack buffer overflow as the CVE description incorrectly states. This may be the first public exploit for a kernel stack overflow, and it turns out to be a bit tricky due to some particulars of the econet vulnerability. It involves the econet_sendmsg function, ec_dev_ioctl function, and the ipc subsystem. Linux kernel versions prior to 2.6.36.2 are affected.

Ubuntu Security Notice 1186-1 - Dan Rosenberg discovered that IPC structures were not correctly initialized on 64bit systems. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. Steve Chen discovered that setsockopt did not correctly check MSS values. A local attacker could make a specially crafted socket call to crash the system, leading to a denial of service. Vladymyr Denysov discovered that Xen virtual CD-ROM devices were not handled correctly. A local attacker in a guest could make crafted blkback requests that would crash the host, leading to a denial of service. Various other issues were also addressed.

Mandriva Linux Security Advisory 2011-029
Posted Feb 18, 2011
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2011-029 - Multiple vulnerabilities have been discovered and fixed in the Linux 2.6 kernel. The X.25 implementation does not properly parse facilities, which allows remote attackers to cause a denial of service (heap memory corruption and panic) or possibly have unspecified other impact via malformed data, a different vulnerability than CVE-2010-4164. The bcm_connect function Broadcast Manager in the Controller Area Network implementation in the Linux creates a publicly accessible file with a filename containing a kernel memory address, which allows local users to obtain potentially sensitive information about kernel memory use by listing this filename. The install_special_mapping function in mm/mmap.c does not make an expected security_file_mmap function call, which allows local users to bypass intended mmap_min_addr restrictions and possibly conduct NULL pointer dereference attacks via a crafted assembly-language application. Various other issues have also been addressed.
